8. Overheating issues
a. What is the junction temperature of each FPGA in the system (one per card)? None should
exceed 100 C (red) in the GUI.
b. What is the measured temperature of the optical transceiver? Does it enter the yellow or red
zones in the GUI?
c. If excess temperature is an issue, better thermal management is required:
i.
Better conductive cooling via mounting standoffs
ii.
Thermal spreaders can be attached to hot components
iii.
Thermal gap pad can be installed below the HDE to push heat to the enclosure, if any.
iv.
In surface systems, airflow should be applied.
9. 914-VDX Expansion channel shows faults
a. Alter the differential voltage in the 914-VDX configuration settings tab in the GUI. Reduce the
voltage for short expansion links, increase for longer links.
b. Are the firmware revisions of the cards compatible? Refer to Section 8.1.
10. Unknown problem:
a. Are all cards in the system shown in the GUI? If not, why? Check #2 above.
b. Using the 914 Diagnostic GUI, open and close tabs looking for anything
‘RED’
, this indicates
a problem that should be addressed.
